Macros are lightweight functions that accept parameters and return a value: just like an ordinary function. They're called from within formulas.
To learn about available macros, see Macro References.
Inside of a formula, macros can be called just like an ordinary function:
Naturally, you can pass variables into macros:
Macros can also be nested within each other
macro1(arg1, macro2(arg2, arg3))
By default, whitespace characters are trimmed off parameters, but this can be prevented by surrounding your arguments in quotation marks
length(Hello ) Output: 5
And if we use quotation marks:
length("Hello ") Output: 6
This works with any type of arguments that you supply including variables and macros.
sum("%VAR_TEN%", "sum("10", "10")") Output: 30
Escaping Quotation Marks
Quotation marks can be escaped using an additional set of quotation marks.
length("") Output: 0 length("""") Output: 2
